On Thursday, the next trough in the Eastern Pacific moves onshore

Basin. By Friday, strong southwest winds of 25 to 35 mph will
develop over much of eastern Utah and extreme western Colorado.
Winds will be strongest across northeastern Utah where the 70 kt upper
level jet will reach. These breezy conditions will continue
through the weekend with some decoupling possible at lower
elevations between the sunset to sunrise time period. Overall
conditions will remain unstable with a shower or two possible over
the weekend, particularly on Sunday. The trough looks to finally
push through as a cold front on Sunday night or early Monday. At
this point there is major differentiation on 700 mb temps by
Monday (5 to 8 degree difference) in the long range models and
timing and extent of precipitation as well. Cooler unsettled
conditions are expected for next week...with temperature closer to
climo than we have been seeing recently.
